Omega offers a robust line of 2-phase biploar
step motors ranging in frame size from NEMA 11
to NEMA 34. Most of our models are the high torque style, with
holding torques up to 1845 oz-in. All motors
conform to industry-standard NEMA mounting
dimensions, and are offered with a range of well-featured,
compatible drives and indexers. With the exception of our
two smallest motors (OMHT11-013, OM5014-842), all of our step
motors are optimized for microstepping: they can achieve
a stepping resolution of up to 51,200 steps/revolution (.007°
per step) when operated by one of our microstepping drives.
Although it is not necessary, these motors can be fitted with one
of our incremental encoders, which can aid in stall detection and
prevention.

Important Note About
Motor Current vs Drive Current:When setting the drive current, you should multiply the
stepper motor's nameplate current by 1.2. This provides
the correct conversion from the motor's full-step
nameplate rating to the drive's current setting.
If the motor nameplate current is specified as 5 Amps,
set the drive current to 6 Amps (5 x 1.2) to achieve
full performance.

Most of the stepper motors are
8-lead motors, offering the flexibility of either series or parallel
connection. The motors should be series connected for best torque
at low speeds, and parallel connected for best torque at higher speeds.
